Extraction of Metals Good Science

Only the least reactive metals, such as gold and silver, exist in their elemental metallic form. These metals are known as native metals. The chemical reactivity of metals also determines their method of extraction. Native metals undergo physical separation processes, such as froth flotation.

2021-11-15  If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
